Here is the best one guy in a ski-mask bursts into a sperm bank with a shotgun. "Open the f*cking safe!", he yells at the girl behind the counter. "But we're not a real bank" she replies, "We don't have any money. This is a sperm bank". "Don't argue, open the f*cking safe or I'll blow your head off". She obliges and once she's opened the safe door, the guy says " Take out one of the bottles and drink it". "But its full of sperm!" she replies nervously. "Don't argue. Just drink it!" he says. She pulls the cap off and gulps it down. "Take another bottle and drink it too", he demands. She takes out another one and drinks it as well. Suddenly the guy pulls off the ski-mask and to the girls amazement it's her boyfriend. " See honey i have been telling you its not difficult to drink sperm?"
